Interactive Self-Study Module: Isothermal Continuous Stirred Tank Reactors (CSTRs)
Overview:

This module uses screencasts and interactive simulations to explain isothermal continuous stirred tank reactors.  It then provides example problems and step-by-step quiz simulations to allow the user to test themselves. We suggest using the learning resources in the following order:

  1. Attempt to answer the multiple-choice ConcepTest and solve the example problem before watching the screencast or working with the simulation.
  2. Watch the screencast that describes isothermal CSTRs and answer the questions within the screencast.
  3. Use the interactive simulation to further understand the isothermal CSTRs.
  4. Try to solve the two example problems before watching the solutions in the screencasts.
  5. Answer the ConcepTests.
Motivation:

 This module is intended for a kinetics/reaction design course.


Before studying this module, you should:

  • Be able to calculate mass balances.
  • Understand rate of reaction and how reaction rates depend on concentrations.

After studying this module, you should be able to:
  1. Describe the differences between a CSTR and a PFR or batch reactor.
  2. Explain why a CSTR might be used instead of a PFR.
  3. Determine the size of an isothermal CSTR for a single reaction to reach a desired conversion, given the rate constant, order of reaction, inlet reactant concentration, and inlet flow rate.
  4. Determine the conversion in an isothermal CSTR for a single reaction, given the rate constant, order of reaction, inlet reactant concentration, and inlet flow rate.
